/* Currencies.
  *
  * A currency (or sometimes called "commodities") is a string which
  * - Begins with either a letter or a slash (/) character.
  * - Contains at least one letter.
  * - Ends with either a letter or a number.
  * - May contain the following special characters within: period (.),
  *   underscore (_), dash (-), or quote (').
  * The pattern has to be kept in sync with beancount.core.amount.CURRENCY_RE.
  *
  * In Beancount v3 (C++ version), a single character (e.g. "V" for Visa) is a
  * valid currency. v2 uses the GNU flex scanner which does not have the
  * lookahead capability required to make this possible but the v3 C++ scanner
  * uses Genivia's RE-Flex which supports a lookahead and it will.
  *
  * Example currencies:
  *   "AAPL" (stock)
  *   "V" (single-character stock)
  *   "NT.TO" (stock on another market)
  *   "TLT_040921C144" (equity option)
  *   "/6J" (currency futures)
  *   "/NQH21" (commodity futures)
  *   "/NQH21_QNEG21C13100" (futures option)
  *
  * Counter-examples:
  * - "/6.3": If a currency begins with a slash, the following pattern has to
  *   include at least one letter. "/6J" is a valid currency, but "/6.3" is not.
  * - "CAC_": A currency cannot end with a special character; it has to end with
  *   either an uppercase letter or a number ("C345" is a valid currency, but
  *   "C_" is not).
  *
  * Note: In this scanner we locate the rule above that matching SLASH on
  * purpose so that a name starting with '/' for a futures contract will match
  * with higher priority than that matching a divide '/' character.
  *
  * Keep in sync with {edefe3fbe907}.
